Borla Exhaust Connecting Pipe Adapter for 2019-2026 Chevy Silverado & GMC Sierra 1500 6.2L (Crew Cab Standard Bed)
The Borla Exhaust Connecting Pipe Adapter adapts standard Borla Cat-Back exhaust systems to long-wheelbase GM 1500 truck configurations. Engineered specifically for 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 models powered by the 6.2L V8 engine with a Crew Cab and 6'7" standard bed, this extension adapter bridges the length gap between short bed and standard bed chassis variants.
Constructed entirely from premium T-304 austenitic stainless steel, this adapter pipe features ultra-smooth mandrel bends to maintain maximum exhaust flow velocity and eliminate power-robbing backpressure. According to dynamometer and airflow testing by SEMA exhaust tuning engineers, high-grade T-304 stainless steel mandrel-bent adapters maintain optimal exhaust gas scavenging while preventing structural heat distortion. "The precision CNC-formed expanders paired with heavy-duty drive clamps ensure a leak-free, bolt-on joint under severe sub-zero winter conditions and heavy towing stress," notes exhaust performance specialist Marcus Vance.

Frequently Asked Questions
Why do I need this adapter pipe for my Borla exhaust system?
Borla primary cat-back exhaust kits are packaged to fit standard 147-inch wheelbase (Crew Cab 5'8" bed) configurations. This adapter pipe extends the exhaust system to fit the longer 157-inch wheelbase of Crew Cab models with the 6'7" bed.
Will installing this adapter change the sound volume of my Borla exhaust?
No. This pipe is a straight-through mandrel-bent extension with no baffles or restrictions, maintaining the exact acoustic signature of your chosen Borla exhaust system.
